I chose my topic to be on the area between the Tigris and the Euphrates
Rivers, also known as Mesopotamia. My purpose is to show how the geography
of this region impacted the beginnings of civilization. This area has long
been the site of the rise and fall of great empires, and I believe the
geography of this region has a lot to do with that.

Mesopotamia is a historical region in southwest Asia where the world’s
earliest civilization developed. The name comes from a Greek word meaning
"between rivers," referring to the land between the Tigris and Euphrates
rivers, north or northwest of the bottleneck at Baghdad. It is known as
Al-Jazirah, or "The Island," to the Arabs (3). South of this lies Babylonia.
However, in the broader sense, the name Mesopotamia has come to be used
for the area bounded on the northeast by the Zagros Mountains, and on the
southwest by the edge of the Arabian Plateau, and stretching from the Persian
Gulf in the southeast to the Anti-Taurus Mountains in the northwest (5).
Only from the latitude of Baghdad do the Euphrates and Tigris truly become
twin rivers, the "rafidan" of the Arabs, which have constantly changed
their courses throughout the ages. This region was the center of a culture
whose influence extended throughout the Middle East and even the rest of
the known world. This paper will focus on the importance of geography in
raising this small region to such a level of high importance in the history
of the world.

The National Standards for Geography are being employed into school
education programs throughout the United States. The source for the standards
is Geography for Life in which they are published. The book suggests
the essential knowledge, shills and perspectives that students should master
by grades 4,8,and 12. One of these such standards is "knows and understands
the physical and human characteristics of places." This is very important
to the extent that people cannot fully understand a place unless they first
understand the environment and native people of a place. I plan to incorporate
this knowledge into my paper for the reader. Another of these national
standards is "knows and understands that physical processes shape patterns
on the earth’s surface." This is also very important in the sense that
this really is the core of geographic knowledge. I will try to incorporate
this in by describing the effects of the twin rivers on this region. Another
standard that I will use is "knows and understands the characteristics,
distribution, and migrations of human populations." This basically means
that we should know how people end up where they are in the world. I plan
on incorporating this point into my paper as well. And a final standard
that I will use will be "knows and understands the changes in meaning,
distribution, and importance of resources." Natural resources are extremely
important in any civilization. I plan to show how vital it was in the shaping
of Mesopotamian history.

Archaeological excavations in Mesopotamia, conducted since about 1840,
have revealed evidence of settlement back to about 10,000 BC. Favorable
geographic circumstances allowed the peoples of Mesopotamia to evolve from
a hunter-gatherer culture to a culture based on husbandry, agriculture,
and permanent settlements (1).
Trade with other regions also flourished, as indicated by the presence
in early burial sites of metals and precious stones not locally available
(6).

Mesopotamia is a flat, fertile land. Between Baghdad and the mouth of
the confluence of the Tigris and Euphrates, where it empties into the Persian
Gulf, there is a difference in height of only about one hundred feet. As
a result of the slow flow of the water, there are heavy deposits of silt,
and the riverbeds are raised. Consequently, the rivers often overflow their
banks, and may even change their course, when they are not protected by
high dikes (7). In recent times they have been regulated above Baghdad
by the use of escape channels with overflow reservoirs. The extreme south
is a region of extensive marshes and reed swamps, called hawrs, which,
probably since early times, have served as an area of refuge for oppressed
or displaced peoples (3).

The supply of water in this region is not regular. As a result of the
high average temperatures and a very low annual rainfall, the ground of
the plains of latitude 35 degrees north is hard, dry, and unsuitable for
plant cultivation for at least eight months of the year. Consequently,
agriculture without risk of crop failure, which seems to have begun in
the higher rainfall zones and in the hilly borders of Mesopotamia in the
tenth century BC, began in Mesopotamia itself, the real heart of civilization,
only after artificial irrigation had been invented. This brought water
to large expanses of territory through a widely branching network of canals
(4). Since the ground is actually extremely fertile and, with irrigation
and the necessary drainage, will produce in abundance, southern Mesopotamia
became a land of plenty that could support a considerable population (1).
The cultural superiority of north Mesopotamia, which may have lasted until
about 4,000 BC, was finally overtaken by the south when the people there
had responded to the challenge of their situation (3).

The first agriculture, the domestication of animals, and the transition
to sedentary life took place in regions in which animals that were easily
domesticated, such as sheep, goats, cattle, and pigs, and the wild types
of grains and leguminous plants, such as wheat, barley, pea, and lentil,
were present (7). Such centers of these things may have been the valleys
and grassy border regions of the mountains of Iran, Iraq, Anatolia, Syria,
and Palestine. As settled life, which caused a drop in infant mortality,
led to the increase of the population, settlement spread out from these
centers into the plains (2).

The present climatic conditions are fairly similar to those of 8,000
years ago (6). A survey of ruined settlements in the area thirty miles
around ancient Hatra has shown that the southern limits of the zone in
which the agriculture is possible without artificial irrigation has remained
unchanged since the first settlement of Al-Jazirah (5).

The availability of raw materials is a historical factor of great importance,
as is the dependence on those materials that had to be imported. In Mesopotamia,
agricultural products were available in plenty and could easily be produced
in excess of home requirements to be exported. On the other hand, wood,
stone, and metal were rare or even entirely absent. Consequently, southern
Mesopotamia in particular was destined to be a land of trade from the start.
Only rarely could empires extending over a wider area guarantee themselves
imports by plundering or conquering neighboring regions (3).

The native raw material that epitomizes Mesopotamian civilization is
clay. In the almost exclusively mud-brick architecture and in the number
and variety of pottery artifacts, Mesopotamia bears the stamp of clay as
does no other civilization. And nowhere in the world but in Mesopotamia
and the regions over which its influence was felt was clay used as a vehicle
for writing (1). This
was an achievement that amounted to nothing less than the invention of
writing (7).

Ancient Mesopotamia had many languages and cultures. Its history is
broken up into many periods and eras. It had no real geographic unity,
and above all, no permanent capital city. By its very variety, it stands
out from other civilizations with greater uniformity, such as Egypt (6).
The script and the pantheon of gods and goddesses constitute its unifying
factors, but in these also Mesopotamia shows its affinity for variety.
Written documents were turned out in quantities, and there are often many
copies of a single text. The pantheon consisted of more than one thousand
deities, even though many names may apply to different manifestations of
a single god (2).

The geography of the region also affected the cycle of kingdoms and
empires. Its terrain promoted foreign invasion and thus brought foreign
influence (4). Babylonia and Assyria lay within a stretch of more or less
fertile soil which, next to the huge arid subcontinent of Arabia. It sweeps
northwest from the marshes and the shores of the Persian Gulf along the
rivers and the ranges of the Zagros to link up to the plateaus and hills
that pile up toward the Taurus Mountains and Lebanon, leading to the Mediterranean
Sea (5). The Euphrates, especially in the last third of its course, sharply
marks off the fertile land from the arid territory extending beyond its
western bank, but the Tigris hardly forms a boundary. This situation, of
course, had its political consequences. The frontiers between Mesopotamia
and the mountain regions that accompany the Tigris to the northeast and
the upper Euphrates to the north never became stabilized. In fact, they
constituted the line of contact between Mesopotamia and those regions that
provided links with the flatlands of inner Asia (7). Through the passes
of these mountains came such essential materials as metals, precious stones,
aromatic matter, and timber, all in great demand in the lowlands, where
increasing prosperity based on agriculture made its inhabitants feel the
lack of such materials (3). These contacts were rarely peaceful.

Toward the southeast, the Persian Gulf formed a frontier that functioned
both as a barrier and an avenue of communication in the course of Mesopotamian
history. It formed shipping lanes through which came new plants and animals
as well as timber and precious stones (7).

The Euphrates, with vast stretches of desert lands on its western bank,
formed the south and southwest border. Due to ecological conditions, contacts
occurred sporadically in the south and, more regularly and effectively,
along the middle course of the river. Through certain corridors of approach,
repeated invasions and a continuous process of infiltration brought smaller
and larger Semitic-speaking tribes into the region between the rivers and
even across the Tigris (6).

During the three thousand years of Mesopotamian civilization, each century
gave birth to the next. Thus, classical Sumerian civilization influenced
that of the Akkadians, and the Ur III empire, which in itself represented
a Sumero-Akkadian mixture, influenced the whole first quarter of the 2ndcentury
BC. Later with the Hittites, large areas of Anatolia were infused with
the culture of Mesopotamia from 1700 BC onward. Contacts, via Mari, with
Ebla in Syria, go back to the 24th century BC, so that links between Syrian
and Palestinian scribal schools and Babylonian civilization during the
Amarna period may have been much older (1).
At any rate, the similarity of certain themes in cuneiform literature and
the Old Testament, such as the story of the Flood or the motif of the righteous
sufferer, is due to such early contacts made possible through geographic
location and not to direct borrowing (3).

Mesopotamian religious thought was also profoundly affected by the geography
of the region. The deities of the earlier Sumerians tended to be local,
centering around the subsistence of the community. A primary concern in
this and later periods was the fertility of the fields, waters, and animals
(2). During this period,
the deity took the form of the natural phenomenon represented. For example,
the deity associated with the rain cloud was pictured as a dark, lion-headed
bird hovering in the sky (6). The Assyrian and Babylonian gods did not
displace those of the Sumerians but were gradually assimilated into the
older system. The gods were seen to be active in the history of the area
and within the changing relationships of the various city-states in the
Tigris-Euphrates Valley. The image of the deity was fed and clothed and
waited upon in a manner analogous to that of the king and his court. Just
as for the king, the primary responsibilities of the deity were fertility
and security (4).

Although the number of deities represented in the Mesopotamian pantheon
numbered in the hundreds, a relatively small number of deities played a
prominent role. Especially important among the older gods were Anu, the
god of heaven, who was the oldest of the gods; Enki, who was the god associated
with water; and Enlil, the earth god who apparently presided over the divine
assembly. Also, as was common in the ancient Middle East, these deities
were associated with particular cities. Particular mountains, trees, rivers,
and even certain man-made items such as the plow were also considered sacred
(5).

Through all these things, it is easy to tell that Mesopotamia is a very
important region in world history. It has long been the center of great
civilizations and peoples. The geography of this area certainly played
a central role in the importance and influence of these lands. Geography
has had a heavy hand in the culture and history of Mesopotamia, as it does
in all areas of the world.
